随着多元新闻主体的不断涌现,新闻业的产制规则和传播逻辑均发生了重大变化,新闻生态系统成为理解当下新闻业变迁的一个有效概念。但这一概念还具有一定的笼统性、模糊性,结合此概念及行动者网络理论的启发,文章拟提出“网络-节点式”新闻生态系统概念,以进一步描摹多元新闻主体涌现后新闻业发生的根本性变化。其生成逻辑与新的新闻行动主体生态位不断提升及职业行动者的中心地位被解构密切相关。在这一系统中,多元新闻主体主要通过协作机制、制衡机制、构造机制、创新机制发生相互作用。“网络-节点式”新闻生态系统对新闻的定义、新闻行业结构、新闻文化均产生了重要影响。
With the continuous emergence of multiple news subjects, the production rules and communication logic of the current news industry have undergone major changes, and the news ecosystem has become an effective concept to understand the changes of the current news industry. However, this concept is also general and vague. Inspired by this concept and the theory of actor network, this paper proposes the concept of "network-node" news ecosystem to further describe the fundamental changes in the news industry after the emergence of multiple news subjects. Its generation logic is closely related to the continuous improvement of the new news action subject niche and the deconstruction of the central position of professional actors. In this system, multiple news subjects interact mainly through cooperation mechanism, check and balance mechanism, construction mechanism and innovation mechanism. The "network node" news ecosystem has had an important impact on the definition of news, the industry structure of news and news culture.
